Subject: [dpdk-dev] DPDK and Link-time Optimizations

Hi.
Did anyone on the list successfully build DPDK with GCC Link-time
Optimizations (LTO) enabled? I tried and failed a while back, although
the detailed reasons of my failure eludes me for the moment.
If LTO builds would work "out of the box", DPDK could gradually migrate
from away from having static inline functions in the header files.
Those interested squeezing out as much performance as possible would
build with LTO (and static linking), and those applications who cared
more about independent upgrades would use dynamic linking and non-LTO
builds. With the extra cost of using DPDK as a shared library
(-fPIC-compiled code, more expensive TLS accesses etc), I'm guessing
this is the case already today.
Regards,
Mattias
